Windows only: Pared-down portable application Radio Sure streams and records more than 12,000 channels of music and other radio feeds. If you can't find something to listen to, you're probably not looking hard enough.

The interface of Radio Sure is straightforward, if a bit cluttered. It starts with a master list of radio stations and a search box to narrow down the stations by genre, country, language, and other name. At the bottom of the window are some basic controls for playing and recording the streams, as well as information about the song if it's embedded in the source.
